Problems solved by technology

[0006] Although the above-mentioned existing light-emitting diode elements already have the function of preventing electrostatic discharge from damaging the light-emitting diode 10, the light-emitting diode 10 must be inverted and fixed on the zener diode 20 during the manufacturing process. Accurate alignment equipment not only consumes cost, but also relatively increases the difficulty of manufacturing
In addition, the Zener diode 20 is used as the base (Submount) of the light-emitting diode 10 in this design, and the volume of the Zener diode 20 is quite large, so a lot of materials and manufacturing costs are wasted.

Description

technical field [0001] The invention relates to a light-emitting diode element, especially a light-emitting diode element that can prevent electrostatic damage, which can not only simplify the production process and improve the production yield, but also increase the service life of the light-emitting diode element. Background technique [0002] Light-emitting diodes are widely used in computer peripherals, communication products, and other electronic devices due to their advantages of small size, light weight, low power consumption, and long life. However, no matter in the manufacturing process or in use, the light-emitting diodes are often damaged due to an electrostatic discharge. Therefore, how to avoid the damage caused by the electrostatic discharge of the light-emitting diodes depends on the design and manufacture of light-emitting diode components. A big point. [0003] see figure 1 , is a schematic circuit diagram of an existing light-emitting diode element with ...
